To ensure that the work environment and equipment create ideal work conditions

To minimise the strain to which people are subjected at work

People and ergonomics.

The most common problem when sitting : sitting with a hunched back

The longitudinal ligaments of the spine and intervertebral disc become increasingly slack and shorter

Shoulder back and neck muscles are subject to static strain

Possible consequences :

Neck pains, back pains,general fatigue

Pressed-in stomach,detrimental effects on digestive organs

Negative effects on the muscles

Lack of concentration and tiredness due to reduced circulation of blood and lymphatic fluid

The remedy from arvand

An ergonomically effective chair must be adaptable to the users individual needs and type of work.

The quality of an office chair thus hinges on its capacity to implement the ergonomic requirements of dynamic seating and to accommodate the users individual anthropometric characteristics, such as weight and size.

Anatomical shaping of the backrest contours in longitudinal and transverse directions and optimum adaptation to users of different sizes and proportions are important in order to ensure that the backrest affords full support .The backrest then effectively relieves the strain on the back muscles and intervertebral discs .

Armrests

Far from being a mere status symbol armrests on an office chair fulfil key ergonomic functions and play a vital role in ensuring well-being ain the workplace :

They afford support when standing up and sitting down (the spine is lowered onto the seats upholstery without jolting)

They relieve the strain on the muscles of the shouders and the upper arms

They relieve tension in the area of the neck and the cervical vertebrae .
